REMOVABLE BODY FOR HAND TRUCKS Filed June 7, 1928 ATTORN EY PatentedJan. 21, 1930 PATENT OFFCE FREDERICK L. JACOBS, OF NEWARK, NEV JERSEYREMOVABLE BODY FOR HAND TRUCKS Application led June 7,

This invention relates to attachments for hand trucks and particularlyto an improved removable body, the object being` to provide aconstruction which will coact with a hand truck for properly supportingloads of different sizes.

Another object of the invention is to provide a removable body for handtrucks, whereby the body may be loaded at a point distant from the handtruck and later engaged by the hand truck for transportation.

Another object, more specilically, is to provide a removable body forhand trucks which is 'formed with side members Constructed to interlockto a certain extent with the hand truck so as to properly be supportedby the truck either when empty or when carrying a load.

In the accompanying drawing,-

Figure 1 is a perspective view of a removable body for a hand truckdisclosing an embodiment ot the invention, the same being shown mountedon a truck;

Figure 2 is a sectional view through Figare 1 approximately on the line2-2, the

same being on an enlarged scale;

Figure 3 is an enlarged fragmentary sectional view through Figure 1 onthe line 3-3 Figure 4 is a fragmentary sectional view through Figure 1on the line 4-45 Figure 5 is an enlarged 'fragmentary seetional viewthrough Figure 1 on the line 5--5.

Referring' to the accompanying drawing by numerals, 1 indicates thetruck as a whole F and 2 and 3 the usual arms of a truck merging intogrips 4 and 5. The arms at the lower end are connected in a suitablemanner and are properly supported by the wheels 6. A reach 7 isConnected with the arms 2 and El in the usual manner and acts to supportthe removable body 8. The parts from 1 t-o 7 inclusive are -old andwell-known and are the usual parts of trucks now in common use, andtherefore form no part of the present invention except in combination.The body 8 is provided with what may be termed a back 9 and a lower endor bottom 10. The bottom 10 is set at the same angle from back 8 asreach is in respect to the arms 2 and 3. In this way the body 8 properlylits against 1928. Serial No, 283,552.

the arms and against the reach 7. rlhe body 8 is iiormed with a numberof boards 11 in back 9 and similar boards 11 in bottom 10. Side bars 12and 18 are provided for the back 9, said side bars being preferablyintegral with the side bars 14 and 15 of bottom 10. Preferably the sidebars 14 and 15 are integral with an end section 16. From this it will beseen that the members 12 to 16 inclusive are all formed trom a singlepiece or metal. In cross-section this metal appears as shown in Figure4- except at the corners 17 and 18 where a single thickness oit metal isprovided, as shown in Figure 8. By bending a piece of sheet metal, asshown, it will be noted that the bar 12 and also the other bars areformed into a rectangular hollovv7 beam 19, as shown in Figure 4, witheXtensions 20, 21 and 22 forming a channel structure into which the endsof the boards 11 and 11 extend. By bending the metal as just described achannel is provided for the boards and a reinforcing and stiifening beamprovided beneath the ends of the boards, so that an exceptionallystrong, rigid structure is provided. All parts of the hollow beam 19 arecut away at the corners 17 and 18, except the outer surface, and as themetal is comparatively resilient this permits the side bars 12 and 14 tobe swung somewhat away rom the side bars 13 and 1o when inserting orremoving any ot the boards 11 or 11. 1n order to hold the side barsrigidly in place so to pinch the ends o1 the boards 11 and 11',clampingl bolts 23 and 24 are provided and act to draw the side barstoward each other and firmly against the various boards. Bolt 23, asshown particularly in Figure 4, extends along the edge oi the uppermostboard 11, wherebv tlfxese boards cannot accidently move out ot place.Bolt 21.1-, as shown in Figure 5, is arranged between the lowermostboard 11 and one ofi the end boards 11', whereby longitudinal movementof the b ards cannot take place, even il the bolts should becomesomewhat loose. llt any or the boards 11 or 11 should become worn orshould be brolen, the bolts may be removed and the side bars spreadapart, said bars springing or hinging at points 17 and 1.8. The boardsmay then be readily removed and new ones substituted and the bars swungback to their former position and bolts 23 and 24 restored. 1n use theparts are arranged in the position 5 shown in Figure l, so that. thetruck may transport the body as desired. If desired, the body may beloaded with merchandise when the truek is at some distant point and thenthe truek may be drawn over to the lo body and the reach 7 slid underthe boards ll b v reason of the fact that the hollow beam lt) supportsthese boards somewhat above the ground. After thus connecting the truekto the body the truck and body may be moved to a desired point and thebody discharged with its load et merehandise. The truek may then bemoved for a second body with a seeond load and so on as often asdesired. In this` wa)v the truck is in substantially eon- ZU tinuolzsuse for transporting purposes, while a number ot bodies may be used tohold the goods until properly disposed of.

lhat I claim is .1. In a removable body for hand trucks, a

5 plurality of bars forming an enclosing' strueture, eaeh of said barsbeing formed to prelsent a substantially rectangular hollow beam and aehannel iron. a plurality oi' independent boards slidably fitted intosaid channel 3u iron, and bolts connecting said bars, said bolts beingrpositioned to prevent any spreading of said bars and any slidingmovement ot' said boards.

A removable body for hand trucks` eomprising an enclosing bar structure,boards held in position by said bar structure, and bolts tor holding thebar structure in position and for preventing any independent sliding`movement of said boards, said bar strne- 40 ture being formed with areetangular supporting hollow beam and a channel for receiving the endsof said boards, said beam beingr positioned to engage said boards nearone end on one face.

A removable body for hand trucks, eomprising a frame having channel ironportions, said frame having a bael( section formed of two parallelmembers and a. bottom seetion formed of a front member and two parHalle] side members swingably eonneeted -to the front member, said twoparallel members of the -baek section being rigidly eonneeted with thetwo parallel side members, whereby all of said parallel .members mayswing, a plurality of boards fitted into the channel iron portions ofsaid baek section and said bottom .section7 and a plurality of boltsconnecting the parts of said frame for elan'iping the frame against theends of said so boards.
